Fix size of preference tree items

* switched the middle arrow buttons from faster/slower to backward/forward to reflect the same functionality as the usual controller window, thus a more consistent GUI. Thanks to the6thReplicant from the forum for the hint.

 * skins2/src/generic_layout.cpp: Fixed an old memory leak
This is a forwardport of [18282]

- Do not leak result from utf8_readdir (ALWAYS strdup'ed).

  * utf8_fopen for: galaktos and snapshots
  * vlc_closedir_wrapper for: webintf, mkv, ncurses and gnutls

  releasing it. mutex locks /= 20 on a standard preparse run
* Only create absolutely necessary variables while preparsing
--> Preparse speed *= 4 (with item in disk cache of course)

* Do not rebuild playlist too much while adding a directory. Add a new flag
  to NodeCreate and Add to control this behaviour

For some unknown reason, wxwidgets 2.6.3 always return WXK_NUMPAD_DELETE
even in case normal Delete key was pressed

Please consider backporting just for Win32 binaries.

Fix m3u export

This might not fix it, but it surely should eleviate the problem.
forwardport of [18324]

  - fspanel centering on right screen
  - fspanel don't hide if mousepointer is over fspanel

* Added a minimal streaming feature

* Add right-click "info" item in qt4 playlist

* Implement MRL handling for file, disc and network
* Moved input slave option to the global dialog (not file specific and
  avoid cluttering the file subpanel)
* Initial implementation of the network panel based on ideas and work by
  Leo Spalteholz. Thanks !
* Improve layouting and handling of the advanced options subpanel

Control & Playback buttons have the same size

Adds an help menu with help and about.
Dialogs are still empty.

whole playlist

you can also do the following now:

<tell app "VLC" to set fullscreen mode to true>, thus you also got write access ;)


Sorry, I just forgot to commit these obvious files in [18115].

* various improvements to the AppleRemote support by Martin Kahr <martin -attt-> martinkahr com> feat. the following changes:
    - holding +/- continuously increases/decreases volume
    - pressing Play twice toggles fullscreen mode
    -  a press on Menu shows the "Position" overlay (like pressing the key
't')

This updates our copy of Martin's unofficial framework to the latest version released.

* added an option to the apple script binding to check for windowed or fullscreen mode. Patch by Martin Kahr <martin --att-- martinkahr com>

Patch by Leo Spalteholz, thanks.

* centre fspanel in the lower third of the screen. additionally, switched style mask to allow dragging in the entire window area (forward-porting [18092])

* the remaining compilation fixes plus a bit of clean up here and there. vout.m needs further fixing and everything needs quite some testing
